Soil pollutants can be broadly divided into two general categories, inorganic and organic. The inorganic pollutants mainly comprise acid, alkali, heavy metals, salts, compounds containing arsenic, selenium and fluorine, and the like, and the pollutants can exist in dust or dust in site construction. Organic pollutants mainly comprise organic pesticides, phenols, cyanide, petroleum, synthetic detergents and the like, and most of the organic pollutants contain Volatile Organic Compounds (VOCs).

A contaminated site soil control apparatus, as shown in fig. 1, comprising: soil conveying component 100, soil pre-repair component 200, soil round paving component 300, and soil finishing component 400. The soil conveying component 100 is used for conveying soil to be repaired, which is excavated from a polluted area by excavating equipment such as an excavator, and the like, and is pre-repaired by the soil pre-repairing component 200 in the conveying process, wherein the soil pre-repairing component 200 is erected above the soil conveying component 100 and is used for pre-repairing the conveyed soil to be repaired by spraying repair liquid medicine. The soil after pre-repair is further uniformly spread into a circular shape by the soil circular spreading component 300, so that the soil finishing component 400 can uniformly spray the finishing liquid medicine to finish finishing soil, the soil after finishing the finishing soil is laterally turned over by the soil finishing component 400 and finally transported back to the polluted site for backfilling by a transport vehicle, and the soil finishing operation is finished.
As shown in connection with fig. 1 and 2, soil conveying member 100 includes a frame 101 and a conveying assembly 102, and conveying assembly 102 is mounted on frame 101 and is used for conveying excavated soil to be remediated. The frame 101 is welded from steel construction and the conveyor assembly 102 is configured as a prior art belt conveyor, although in other embodiments the conveyor assembly 102 may be configured as a material conveying structure other than a belt conveyor.
As shown in fig. 2, a soil pre-repair member 200 is erected above the conveying assembly 102 and is used for pre-repairing the conveyed soil to be repaired. The soil pre-repair component 200 comprises a mounting frame 201, a spray pipe 202, a power component and a first liquid medicine supply component, wherein the power component is not marked in fig. 2, the power component can be configured into a motor driving structure in the prior art, the spray pipe 202 is driven by a motor to rotate on the mounting frame 201, and other driving schemes in the prior art can be realized in the implementation of the power component; the first fluid supply assembly of the soil pre-repair unit 200, which is a tank structure for storing pre-repair fluid, is also not shown in fig. 2, and the fluid in the tank or the fluid tank is supplied to the shower 202 by being filled into the shower 202, which is a conventional means of the prior art, and is not repeated in fig. 2. In terms of the liquid medicine supply speed, it is preferable that the liquid medicine is not filled in the shower pipe 202 when the shower pipe 202 is operated, but only one third or half of the liquid medicine is filled in the shower pipe 202, so that the upper shower holes 203 do not spray the liquid medicine when the shower pipe 202 is operated, and the uniformity of spraying is affected.
In the invention, the spray pipe 202 is of a circular pipe structure, two end surfaces of the spray pipe 202 are parallel to each other and form a certain included angle with the vertical plane, the cross section of the spray pipe 202 along the length direction of the spray pipe is of a parallelogram shape, one end of the spray pipe 202 is rotatably arranged on the mounting frame 201 through a rotating shaft structure and is driven to rotate by the power assembly, and the first liquid medicine supply assembly supplies soil remediation liquid medicine into the spray pipe 202; the shower pipe 202 is provided with shower holes 203 uniformly along the length direction.
In this embodiment, the angle between the end surface of the shower pipe 202 and the vertical surface is 10 degrees to 45 degrees. The shower pipe 202 is provided with a plurality of rows of shower holes 203 uniformly along the circumferential direction. The gap between the spray holes 203 is 1 cm-20 cm along the length direction of the spray pipe 202, and the gap between the spray holes 203 is 5 degrees-20 degrees along the circumferential direction of the spray pipe 202.
The shower pipe 202 using this structure has an advantage in that the interval between adjacent shower pipes 203 can be enlarged based on the same standard of the shower density, while ensuring a larger shower density. If the spray head in the prior art or the drip pipe in the prior art needs to strengthen the spray density, the quantity of the spray heads needs to be increased or the drip holes of the drip pipe are densely arranged, the spray heads are wasted, the cost is high, too many holes of the drip pipe are caused by too many drip holes, the bearing capacity is not strong, and the drip pipe is easy to damage. The inclined tube type spray pipe 202 can ensure good spray density.

The rotating shaft assembly 303 is arranged at the bottom of the middle of the cross rod 302, and is used for enabling the cross rod 302 to rotate above the rotating shaft assembly 303 and driving the two round tables 3011 in the rotating round table assembly 301 to mutually change positions, so that the precision repairing operation and the soil overturning and dumping operation are facilitated. The radius of the circular table in the rotary circular table assembly 301 is equal to the width of the conveying assembly 102, and the discharge hole of the conveying assembly 102 coincides with the radius of the circular table in the rotary circular table assembly 301, so that when the circular table 3011 rotates for one circle, soil just spreads over the circular table 3011.
